To all iii/ 10m. it may concern:

Be it known that I, hlAURIOE L. SMOCK, a citizen of the United States, residing at Souihport, in the county 01' Marion and State or indiana, have invented new and useful Improvements in Seed-Planters, of which the following is a specification.

This invention. is an improved guiding and supporting device for use in connection with an a ricultural machine, such as a grain drill or planter of other form, the object of the invention being to provide means whereby the operator who walks in rear of the ma chine may readily guide and control it, as hereinafter described and claimed.

In the accompanying drawings: l igure l is a perspective view oi a guiding and supporting device constructed in accordance with my invention, showing the same attached to a one horse grain drill. Fig. 2 is a detailed vertical longitudinal sectional view of my improved guiding and supporting device on line 22 of Fig. 3. Fig. 3 is a detailed plan 01' the same. Fig. 4t is a detailed view being partly a transverse section and partly a rear elevation.

The grain. drill or other form of planter in connection with wnich my improved guiding and supporting device is adapted to be used may be of any ot' the usual forms and is here shown a one horse grain drill provided with adjustable rear supporting wheels (1 and a number of angularly arranged beams l) which are appropriately spaced apart.

In accordance with my invention, 1 provide a beam 1 which is disposed and secured between two of the beams (1 so that the said beam 1 extends under the center at the grain drill and also projects l'orwardly and rea'n'wardly therefrom. .A pair of handle bars 2 3, extend rearwardly and upwardly from the rear end ol the beam 1 their lower ends being secured to opposite sides thcreol'. The handle 4 of the handle bar 3 is hinged or pivotally connected thereto as at so that the said handle may be disposed either in line with the said handle bar 3 or at any desired angle thereto. At the upper side of the beam 1, at a suitable distance from the front end thereof, is a yoke 6 which is provided with a centrally disposed downwardly extending pin 7 which passes through an opening in and pivotally mounts said yoke on the beam 1, and at the ends 01' said yoke are upwardly extending bearings 8, in which a rcvolvin g axle shaft 9 is mounted. On the 3 center of the said shalt, midway between l the bearings S, is a gear wheel 10, the periphoral lace of which forms the segment of a sphere and is provided with convex spur teeth 11. On the ends of the said axle shalt are supporting and guiding wheels 12. ()n the beai'n 1 at a suitable distance in rear 01 the pivotally mounted yoke (3 is a plate 13 secured by bolts 14 and which is provided with upturned side bearings 15 in which are mounted the journals or axles of gears .16, 1.7 The gear 16 has a concave peripheral spurred face the radius of which coincidcs with that of the convex face 071' the gear 10 and is engaged by said gear 10. The gear 17 is similar to the gear 1.0 and has a convex peripheral face which forms the segment of a sphere.

It will be understood from the foregoing and by reference to Fig. 3 of the drawings that owing to the provision ol the convex face of the gear 10 and the matching concave face of the gear .16 said gear 10 is kept in engagement with said gear 16 whether said gear 10 is in line with or at an angle, within certain limits, of the gear 16, and hence the yoke (i which is pivotally mounted and which carries the rear supporting wheels and their axle shalt may be disposed at any angle with reference to the beam 1 that is required in order to properly guide or direct the machine. Furthermore it will be understood that the gear 16 with the concave lace an idler which serves to transmit power and motion to the gear 17 from the gear 10. On one end of the shaft 18 of the gear 17 is a sprocket wheel 19 which is connected byan endless sprocket chain 20 lo a driving gear, not here shown, but which is 01 usual conslruraion ol' the grain drill or other planter. lit will be nndcrstoml that the gear 10 is revolved by the wheels Y12, and axle shaft 9 transmits motion to the gear 17 by means of the gears 11, 1G, and that the sprocket wheel 19 which revolves with the gear 17 serves, by means ol the endless sprocket chain, to drive the seed l dropping mechanism ot the planter or grain drill.

An arm 2] projects from one side ol' the pivotally mounted yoke S which has the bearings for the axle shalt. A rock link 22 depends from and has its upper end pivotally connected to the handle bar 3, as as 23. The lower end ot this rock link is connected by a rod 24 to the arm 21. An arm 25 exill-ll
